URLs

A URL (Uniform Resource Locator) is a standardized address used to locate and access resources on the internet, such as web pages, files, or services. It specifies the protocol, domain, path, and optional parameters to uniquely identify a resource. URLs are fundamental to web navigation, linking, and API interactions in software development.

Also known as: Uniform Resource Locator, Web Address, URI, Link, Endpoint

Why learn URLs?

Developers should understand URLs to build and interact with web applications, APIs, and networked systems, as they are essential for routing, resource management, and data exchange. Use cases include configuring web servers, implementing RESTful APIs, handling hyperlinks in front-end development, and parsing query parameters for dynamic content.
